    //  Send the POST
    //  You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
    //  Using quoted-printable, we can easily see the binary bytes for the accented chars.

    //  %82oszenie</pre>
    //  --------------------------------------------------

    //  We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

    //  -----------------------
    //  However.. we can change the charset used for the HTTP request by specifying the request object's charset.

    //  Sample output...
    //  You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250)
